The AirTAC AirTAC SAI200X270-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 270mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI200X270-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708N push force and 15080N pull force at 0.5 MPa, this 200mm bore unit is built to move massive loads. The 270mm stroke provides the travel needed for large presses, lifting rigs, and heavy material handling. As a genuine extruded aluminum profile barrel design, it omits traditional tie-rods for a sleeker body while maintaining strict dimensional interchangeability per ISO 15552 standards.
This specific configuration includes a piston magnet (-S) for direct compatibility with CMSE and DMSE reed switches, which mount seamlessly into the dual sensor grooves on both sides of the barrel. The standard carbon steel piston rod ensures high tensile strength for industrial loads. It features tapered PT port threads and adjustable air cushions at both ends to decelerate the heavy piston smoothly over the 270mm travel, operating efficiently at speeds of 30-500 mm/s.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the 15708N push force required to form thick metal sheets and operate large mechanical stamping presses.
Actuates heavy-duty diverter arms and large sorting gates on primary mining or aggregate conveyor lines.
Drives robust lifting and positioning platforms for heavy machinery assembly, utilizing the 270mm stroke for elevation changes.
Selecting this 200mm bore cylinder is ideal when applications require extreme thrust that smaller bores cannot provide, such as stepping up from a 160mm bore (which offers 10053N push at 0.5 MPa) to achieve the 15708N available here. Because the 270mm stroke is substantial, designers must account for rod-bearing bending under side loads; utilizing an external guide rail or a fully guided cylinder carriage is critical to prevent premature seal wear and rod deflection.
For any mechanism that must hold a load in place during an air pressure drop or valve centering, remember that the standard adjustable air cushion only decelerates the piston at stroke end and does not act as a brake. The piston will drift without live pressure. For positive load holding without continuous air supply, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead. This model's ISO 15552 mounting interface allows drop-in replacement interchangeability with other ISO 15552 cylinders, utilizing standard PT G3/4 ports and accessories like FA flanges or TC trunnions.
Quick checklist
At a 0.5 MPa operating pressure, this 200mm bore cylinder generates a push force of 15708N and a pull force of 15080N. At 0.7 MPa, the push force increases to 21991N.
Yes, the SAI200X270-S is dimensionally interchangeable per the ISO 15552 mounting interface. You can drop it in as a replacement for other ISO 15552 profile cylinders using standard mounting accessories and G3/4 ports.
